' Be it known that I, FERDINAND H. LANGE, Jr., a citizen of the United States, residing at Wilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Sliding-Door Hanger, of which the following is a specification.

The invention relates to improvementsin sliding-door han ers.

- The obj ect of t e present invention is to improve the construction of sliding-door hangers and to provide an exceedingly simple and inexpensive one of great strength and durability designed for use in houses, barns, and

elsewhere and capable of being readily applied to a door and adjusted to fit the same.

l A further object ofthe invention isto provide a sliding-door hanger of this character -which lwill be noiseless and which Vwillbe effectually revented from jumpingthe track.

With t ese and other objects m view the invention consists in the construction and novel combination and arran ement of parts hereinafter fully described, il ustrated inthe vaccompanying drawings, and pointed out in the claims hereto appended, it beingunderstood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be `resorted to Without departing from the spirit I. or sacrificing myy 0f the advantages of the irlvention. Y f

In the drawings, Fi ure 1 is a side elevationA of aslidin -door' anger constructed in accordancel wit this invention and shown a plied to a door. Fig. 2 is a plan .view of tfie same.' Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 1. Fig. 4 is a de? tail viewof one of the blocks which forms the seats for the shaft or axle. view of the shaft ori axle. Fig. 6 is a detail sectonal view taken on the line v6 6 of Fig. 2.

Like numerals of reference designateloorresponding partsin all the figures of. the

walls'or supports. nstead of threading the side walls of the groove.

Fig. 5 is a detailv ends of the pipe or tube the latter may be se'L cured within the annular flanges of the disks or plates by any other suitable means. In the accompanying drawings the invention is applied to a sliding door 6 but' it maybe readilyapplied to a pair of slidin doors, as will be readily understood, and w en a pair of pipes or tubes are em loyed their adjacent ends may be connecte and supported by a hanger of any desired construction. Also instead of employing disks or plates 4 and sockets 3 any other suitable means may be used for supporting the ends of the track.

The slot 2, which extendsalong the track a distance to permit the necessary movement of the door, receives a central annular flange .7 of a wheel 8, which is provided with a grooved peripherypresenting concave faces 9 to the adjacent portions ofthe pipe or tube and conforming to the-'configuration of the same. The -central annular flange extends through the to of the track and preferably bears against t e inner face of the bottom of the same and assistsin sustaining .the weight 'of the door. The flange 7 divides` the groove of the wheel or roller into two separate spaces, and it projects beyond the peripheries of the The wheel is provided .with a central opening 10, through which asses a shaft or axle 11, having slot-' ted or ifurcated ends 12 for the reception of hanger-rods 13, extending from the shaft or axle to the door, as clearly'shown in'Figs. -1

and 2 of the drawings. The shaft or axle extends from opposite sides ofthe wheel, which is arranged between washers 14, held against the wheel by pins orV keys 15 ,as indicated in Fig. 3 of the drawings.

In order to reduce the friction to a minimum, the wheel is provided at its center With an annular chamber 16, forming a'ball-race for the reception of antifriction-balls 17, and in order to enable theparts to be readily assembled the wheel is preferably divided longitudinallyat 13 in the plane of one o f the side faces of the -central ,annular flange 7 to form two sections, as clearly shown in Fig. 3.

The sections may be secured together in any desired manner after the parts have been assembled.

The hanger-rods 13, which are arranged at a slight inclination and which have their up-4 per ends fitted in the slots or bifurcations of the ends of the shaft or axle, are held against lateral movement by pins `or keys 19, which pierce theA ends of the axle beyond the rods TIO same and is practically noiseless.

and which are secured in position after the rods have been placed in the slots. The upper ends of the rods are threaded for the reception of nuts 20,'and blocks 21 are interposed between the nuts and the axle or shaft. rlhe blocks, which are perforated for the reception of the rods, are provided with grooves 22 to form seats for the axle or shaft. Instead of providing threads and nuts any other suitable means may be employed for retaining the' blocks on the upper ends of the rods.

The hanger-rods, which are located at opposite sides of the track, extend in opposite directions from the axle or shaft, and their outer ends are bent at a slight angle and are arranged horizontally in sleeves or eyes 23 of attachment-plates 24, which are secured to the upper edge of the door, adjacent to the side edges thereof, as clearly shown in Fig. 2. The lower orv outer ends of the rods may be provided with nuts 25, or any other suitable means may be employed for securing them to the attachment plates. The attachmentplates are detachably mounted on the upper edge of the door, each plate being provided with a depending boss 26, centrally arranged and having a threaded bore 27 therethrough. Screws 28, passing through the plate, engage the door. A keeper-roller 29, bearing against the under side of the track, isjournaled to and between spaced upstanding ears '30, carried by the upper end of a stem 31, that is threaded through the bore of the boss 26 and preferably extends downwardly into a socket 32, formed in the upper edge of the door. Thus adjustable connections are provided between the outer ends of the hanger-rods 13 and the opposite upper corners of the door. The peripheral grooved wheel, which presents oppos'itely concavely curved faces to the round track, conforms to the configuration of the In order to limit the movement of the door, the track is provided with a stop 33, consisting of a cushion or buffer of rubber or other suitable material, mounted on a shoe 34, which extends upward from a plate 35. The plate 35 is secured by a screw or other suitable fastening device to the track, and the shoe and the buffer are curved to conform to the configuration of the wheel and preferably extend to a point above the center of the same. The stop may be mounted at any desired point and is adapted to prevent the hanger from being injured.

It will be seen that the sliding-door hanger is exceedingly simple and inexpensive in construction, that it possesses great strength and durability, and that as the door is suspended from the supporting-wheel by the hangerrods, which are located at opposite sides of the track, the hanger is effectually prevented from leaving the latter. In view of the fact that a single supporting-wheel is employed,

.6 5 it will be evident that there is a tendency of the door to swing upon the axis of rotation of said wheel. This is prevented by the rollers 29, and said door may be hung properly, so as to avoid any binding action or undue frictional engagement. The wheel is provided with bearing portions at both the top and bot tom of the track, and there is no liability of it jumping the same.

Having thus fully described my invention, what l claim as new, and desire to secure by Letters Patent, is-

1. A sliding door han er, comprising a hollow track provided at t ie top with a slot, a supporting-wheel having a )eriphery conforming to the configuration o the track and provided with a projecting iange arranged to run in the slot, and means for suspending a door from the supporting-wheel.
